The most important milestones from the very beginning until today
Start of drilling work for the doublet well in Laufzorn. The rule of thumb says that the temperature of the thermal water increases by three degrees Celsius for every 100 metres of depth. That means: the deeper it is, the hotter it gets.
Discovery of the well. The production well, from which the hot water is brought up, reaches the water-bearing Malm at a depth of 3,755 metres. The reinjection well, which returns the cooled water into the ground at a distance of around 2 kilometers and a depth of 3,428 meters.
